The NCP1248AD100R2G from ON Semiconductor is a fixed-frequency current-mode controller specifically designed for flyback converter applications. This IC features a switching frequency of 100 kHz and operates within a supply voltage range of 8.9V to 28V.
Key features include an 80% duty cycle, comprehensive fault protection including current limiting, over load, over power, over temperature, and over voltage. It also offers a 10 ms soft-start time and a no-load standby power consumption of less than 30 mW. The device is suitable for isolated output topologies.
This controller is housed in a 7-SOIC package and is designed for surface mount applications. Its robust design makes it an excellent choice for AC-DC adapters for notebooks, LCDs, printers, and offline battery chargers.
The NCP1248 controller integrates a Dynamic Self-Supply function, simplifying the design of the auxiliary supply and VCC capacitor. It also includes a high-voltage current source with brown-out detection and an X2 capacitor discharge feature for EMI filter applications.
